To all w hom itjnay concern:

Be itknown that I, BERTELL KING, a, citizen of the United States, residin at 3 Brooklyn, county of Kings, State'of' 'ew York, have made a certainnew and useful Invention in Explosive-Engines, of which the. following is a specification.

This invention relates to explosive engines, and preferably to engines of cycle type.

The object of the invention is to provide an explosive engine of the type referred to which is simple in construction, efiicient in operation and economical to manufacture.

A further object of the invention is to provide a rotary valve construction of simple design for controlling the admission of explosive mixture to the engine cylinders and the exhaust of the products of explosions from the cylinders.

Other objects of the invention will appear more fully hereinafter. l p

The invention consists substant ally in the construction, combination, locationand relative arrangement of parts, all as will be more fully hereinafter described,'as shown in the accompanying drawings and finally pointed out in the appended claims.

Referring to theaccompanying drawings and to the various views and reference signs appearing thereon, Figure 1 is a view in elevation, parts broken out and parts in vertical section showing a four cylinder engine of the vertical cylinder four cycle type and the valve mechanism therefor and its operating means constructed in accordance with the principles of my invention. Fig. 2 is a vertical section of the same on the line 2, 2 Fig. 1 looking in the direction of the arrows. Fig. 3 is a broken view in central longitudinal section of the rotary valve cylinder embodying my invention. Fig. 3 is a 'view in transverse section on the line 3", 3,

Fig. 3, looking in the direction of the arrows.

Fig. 4.- is a broken view in top plan showing the supply and exhaust port connections for a pair of cylinders of the verticaltype. Fig. 5

is a vertical broken view in central section on the line 5, 5, Fig. 4, looking in the direction of the arrows. Fig. 6 is a broken vertical transverse section on the line 6, 6, Fig. 5 looking in the direction of the arrows. Fig. 7 is a similar view on the line 7, 7, Fig. 5 looking in the direction of the arrows. Fig. 8 is a similar view in horizontal section on the four j the line 8, 8, Fig.6 looking'in the direction of the arrows. In the drawing A, B, C, D designate cylmders, shown in this instance as vertical cylinders of the four cycle type. My in vention, however, as defined in the claims, is

not to be limited or restricted to the number of cylinders shown nor to' cylinders of the vertical type. j

In each cylinder operates a piston E connected by piston rods F to the crank G on Patented July 20,1915.

the main crank shaft H in the usual manner. In the form shown for illustrating the 7 principles of my invention, the 'cranks are inclosed within a crank chamber J.

If desired the, cylinders may be suitably jacketed as indicated at K, but this is a detail to which my invention is not to be limited or restricted.

Reference letterL designates the carbureter well known type of construction such as are usually employed in connection with ex-' .losive engines. The manifold pipe M and its branches N load from the carburetor and deliver, in the usual manner, to the supply ports P to the engine cylinders. Where only two cylinders are employed the manifold M will have only one supply pipe connection N to a supply port P which 1s common to both cylinders. Where three or four or more cylinders are employed, the manifold will have the necessary additional distributing pipe connections N.

In practice and in accordance with my.

invention the explosive mixture is designed to be supplied to a pair of cylinders from the carbureter through any suitable or convenient arrangement of manifold connections, themembers of each pair of cylinders receiving the supply of explosive mixture through 'a common supply port.

At the outer, or in case of engine cylinders of the vertical type, at the upper ends of the cylinders,'and preferably, though not necessarily, cast integrally with the cylinder castings on the tops thereof is the valve casing 10, which, if desired, and preferably may also be jacketed as indicated at 12 for cooling purposes. This casing extends transversely across the ends of the cylinders and communicates freely with the interior of the cylinders through the passages 13. The supply ports P also deliver into the chamber of the valve casing 10. Similarly ex- 15 which may be of any ordinary suitable or haust ports R deliver from the valve casing chamber through exhaust pipe connections S. Extending longitudinally through the chamber of valve casing 10, and journaled to rotate therein is the valve 14, which, as shown, is in the form of a cylinder which may be of-snfiicient length to extend transversely across all of the cylinders of the engine and of sutticient'diameter to perform the function of a valve to control the sup-' cated at a point between two adjacent cylinders. The cylinder valve 14 is provided with transverse diagonally inclined passages 16, 17. In the particular form shown, to

which, however, my invention is not to be limited or restricted, the passage 16 during each completeaxial rotation of the valve cylinder 14:, successively opens connection between the cylinder supply port P and the interior of the cylinder A and also from the interior of said cylinder to the exhaust port R. a 7

Similarly each passage 17 during an axial rotation of the valve cylinder successively opens connection from the same supply port P to the interior of the cylinder B, for instance, and from said cylinder to the exhaust port R. With this arrangement of the inclined passages 16, 17, for each pair of cylinders, it will be observed that the passages 16, 17 by reason oftheir diagonal or inclined relation with reference to each other and by reason of cooperating with the same supply and exhaust ports, have one end of each brought into comparatively close proximity to each other while their other ends, which cooperate respectively with the openings or passages 13 into the cylinders A, B are comparatively widely separated from each other. The two ends of each passage are respectively diametrically opposite each other, that is, they terminate at diametrically opposite though laterally displaced points in the periphery of the valve cylinder in the particular form shown.v and while this arrangement secures an etlicient timing of the cycle of operation, my invention as defined in the claims is not be limited or re stricted in this respect. Of course it will be understood that the passages 16 and 17 are not only longitlulinally inelined relatively to each other but they have no connection with each other at any time and preferably during approximately one half of each they are arranged in planes atan angle of 90 degrees with reference to each other transversely througuh the valve cylinder. Of course it is obvious that any desired arrangement and relation of the valve passages 16, 17 appropriate to any desired cycle or condition may be employed.

\Vith the arrangement above described, and as shown in the drawings, as a practical embodiment of my invention, it will be seen a that the supply port P is in connection with cylinder A during approximately one quarter of a complete rotation of the valve cylinder and said supply port-is in connection with cylinder 13 during approximately another quarter of a rotation of the valve cylinder, the displaced relation of these quarter portions of rotations of the valve cylinders being within the discretion or desires of the designer and dependingiipon the relation of the cranks of the respective cylinders. Similarly the cylinders A and B are in respective connection with the exhaus port It during approximately quarter turns of the valve cylinder and both the exhaust and supply ports are closed to said cylinders complete revolution of the valve cylinder. This will be the relation where the drive gearingv for the valve cylinder is so proportioned as to give one complete rotation to said valve cylinder for each two complete revolutions of the main drive shaft H. While the valve cylinder may be rotated in any suitable or convenient manner, I prefer to drive said valve cylinder through suitable gearing connections indicated at T, see Fig. 1, from the main shaft H of the engine so as tosecure proper timing of theoperation.

It is to be understood that my invention a in its broadest scope as defined in the claims is not to be limited or restricted to any particular location nor to any particular number of valve mechanisms. v

Having now set forth the objects and nature of my invention and a construction embodying the principles thereof, what I claim as new and useful and of my own invention and desire to secure by Letters Patent of the United States is:

1. In an explosive engine, and in combination with the engine cylinder, a piston andcrank shaft. and a supply and'exhaust port for the cylinder, of a valve casing, a rotary cylinder journaled therein and having a transverse longitudinally inclined passage therethrough to form and control the communication between the cylinder and both the supply port and exhaust port and means for rotating said valve cylinder.
